title: Alleviation of kidney damage induced by unilateral ureter obstruction in rats by Rhodiola rosea.
abstract: OBJECTIVE
  To evaluate the efficacy of Rhodiola rosea extract in terms of alleviating the renal damage induced by unilateral ureter obstruction (UUO) in rats.
  
  
  METHODS
  Thirty Wistar albino male rats were divided into five groups: (I) Control, (II) UUO 7 days, (III) UUO 7 days+extract,(IV) UUO 14 days, and (V) UUO 14 days+extract. Seven or 14 days after the initiation of the experimental procedure, the left kidneys of rats in all five groups were removed for histological examination, and their blood was drawn for biochemical measurements.
  
  
  RESULTS
  Median malondialdehyde (MDA) and glutathione peroxidase (GPx) levels were, respectively, 39.4 (5.04) nmol/mL and 25.8 (8.01) nmol/minute/mL in group I, 77.9 (12.38) nmol/mL and 5.8 (1.95) nmol/minute/mL in group II, 48.7 (12.1) nmol/mL and 9.1 (2.3) nmol/minute/mL in group III, 58.5 (23.83) nmol/mL and 8.4 (2.1) nmol/minute/mL in group IV, and 44.8 (4.97) nmol/mL and 13.8 (3.73) nmol/minute/mL in group V. There was a statistically significant difference among the groups in terms of MDA and GPx levels (p<0.05 for both). The median numbers of apoptotic cells were 1 (1), 8 (2.25), 3 (1.25), 23.5 (9), and 7 (I) in groups I, II, III, IV, and V, respectively. There was a statistically siginificant difference among the groups in terms of apoptotic cell number (p<0.05).
  
  
  CONCLUSIONS
  R. rosea extract was shown to alleviate the renal damage induced by UUO through its antioxidant effects. The mechanism by which R. rosea extract causes these effects merits further investigation.
